Abstract
A radial position sensor that measures a radial position of a rotor within a stator is provided. The radial position sensor provides measures the radial position of the rotor along a first axis radial to a rotation axis of the rotor and along a second axis perpendicular to the first axis. The radial position sensor includes four magnetic poles, among which two poles are diametrically opposed along the first axis and two other poles are diametrically opposed along the second axis.
